Reset state trackers for model. Note that we do not actually zero out attributes such as optimizer, but instead rely on the expectation that all of the attrs will be over-written on calling build/compile/etc. This is somewhat fragile, insofar as we check elsewhere for the presence of these

  Note that we do not actually zero out attributes such as optimizer,

  we reset key attributes here to allow building and compiling.
